Tuberculosis: One of the Biggest Killers of All Time

Fri, 07/12/2019 - 8:30am

Throughout human history, it is estimated that over 1 billion people have succumbed to Tuberculosis. The deadly bacterial infection targets the immunocompromised population as well as those who have weakened their lungs through smoking.  It is believed that the first cases of tuberculosis appeared over 17,000 years ago in the wild by infecting bison. There is also a theory that puts the disease in humans around the same time. But, it is unclear whether humans or bison were the first carriers of Tuberculosis.

Friday fold: Wiltondale, Newfoundland

Fri, 07/12/2019 - 5:23am

Here is an outcrop of folded limestone along route 430 in Newfoundland, inside Gros Morne National Park, just west of the crossroads called Wiltondale: A detailed look at the left antiformal portion of the outcrop: A zoomed-in examination of the rightmost part, where a goopy looking synform resides: Just down the way, a second outcrop shows another fold with the same sense of asymmetry, on a smaller scale: Happy Friday …

Sols 2463-2464: A fountain of data

Thu, 07/11/2019 - 10:20am

Curiosity continued work on and around the gorgeous outcrop pictured above that was started on Sol 2461. The layers of the outcrop - with their different colors, textures and thicknesses - tell us a story, one we worked to decipher in this plan with our full complement of contact and targeted science instruments.

Transmission of Leprosy in the US via Armadillos

Thu, 07/11/2019 - 8:30am

Repeatedly referenced throughout the Bible, leprosy, also known as Hansen’s Disease, may often be perceived by the general public to be an ancient disease that has ceased to endanger the modern world.  Much to the misfortune of people living in Africa, Brazil, India, and the Philippines, where the majority of outbreaks occur, nearly 700,000 people throughout the globe annually contract leprosy.

Using sand models to explain the concept of geologic mapping

Wed, 07/10/2019 - 10:33am

Geologic maps can be very visually engaging, but non-geologists may find it difficult to extract the information that a map is supposed to communicate.... Cross sections included with a map can help, but it can still be tough to pull it all together if you don’t look at this sort of material all the time.

Hey, farmer, farmer, put away the DDT now

Wed, 07/10/2019 - 8:30am

Music has often been used as an outlet for activists to reach a broader audience on issues concerning politics, social issues, and environmental crises. Joni Mitchell was a prominent and very influential recording artist in the 1970’s that embodied this idea of using music to educate the public.  One of her most popular songs “Big Yellow Taxi,” called out various environmental issues like deforestation and, what stood out the most to me, the use of DDT.k

Scientists Tackle Grand Challenges In the Earth and Space Sciences In New Special Centennial-Themed Collection

Tue, 07/09/2019 - 9:00am

One hundred years ago when AGU was founded there were still large unmapped places on our planet and the idea of a person stepping on the moon was a dream. Discovery and wonder have characterized the last 100 years of science as we learned the plates shift, the climate changes, and scientists are studying the Moon, Mars, and beyond in detail. Our species now has a global view of how …

Human Rabies Mortality in India: Why Is This Still An Issue?

Tue, 07/09/2019 - 8:30am

There are an estimated 25 million stray dogs within the country of India. These animals serve as carriers for one of the deadliest diseases in the world - one that has ravaged the country and surrounding areas within Southern Asia. This disease is rabies, and India makes up 36% of the world’s rabies deaths each year. About 30% to 60% of rabies victims within countries where the disease is endemic are children under the age of 15. Some of them don’t even know they’re infected until symptoms begin to show and it’s too late.

Urban water underground: How green infrastructure makes it visible

Mon, 07/08/2019 - 1:27pm

When it comes to protecting the water resources that sustain society and the natural environment, it is perhaps unsurprising that groundwater is the part of water cycle that most folks tend to ignore.

Cicadas + Magic Mushrooms = ?

Mon, 07/08/2019 - 8:30am

Magic mushrooms, also known as shrooms, are not allowed for human consumption, but cicadas are also experiencing the same drugs via a different route. Does it affect them the same as it does humans?

Monday Geology Picture: Travertine Wall

Mon, 07/08/2019 - 7:06am

Wow, the past couple of months have been busy! I spent most of May and June travelling for work. Life has calmed down now, so it’s time to resume my blogging… and try to stick with it a little better for the rest of the year! To kick off some blogging, here’s a picture of a beautiful decorative travertine stone on the front of a building. I took this picture …

The Northwest (NW) and Northnorthwest (NNW) outlet of the Penny Ice Cap in 1991 and 2019 Landsat images. Red arrow indicates the 1991 terminus location. Point 1 is a large proglacial, Point 2-4 are areas of emerging and expanding bedrock amidst the ice cap. The two largest outlet glaciers of the NW quadrant of the Penny Ice Cap feed the Isurtuq River.  In 1991 both outlet glaciers terminated at 600 …

It’s Not Easy Finding The Shadow of the Moon

Sat, 07/06/2019 - 3:09am

When the Moon blocks the sun during a solar eclipse, there isn’t a big difference between 70 and 90%, but the difference between 99 and 100% is jaw-dropping! It’s something you remember for the rest of your life. I’ve now seen it twice. My first was two years ago near the Wyoming/Nebraska border, and number two was this past Tuesday near La Serena in Chile. I traveled to Santiago to …
